Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If real-time image analysis is performed to control sound and image output, then automatic optimization capability is improved, but power consumption increases significantly
Solution Approach 1:
The patent implements periodic screen capturing at specific intervals rather than continuous real-time analysis. The processor captures screen content at predetermined time points and performs image analysis only on these captured frames, transforming continuous power-consuming analysis into periodic operations that reduce overall energy consumption while maintaining automatic optimization capability.
Solution Approach 2:
The patent applies image analysis selectively to captured screen content rather than analyzing all visual data continuously. By performing analysis only on periodically captured frames and applying changes only when analysis results indicate optimization opportunities, the system achieves automatic optimization with reduced computational overhead and power consumption compared to continuous full-analysis approaches.
2Measurement precision
If screen capturing frequency is increased to improve detection accuracy, then image analysis precision is improved, but power consumption increases
Solution Approach 1:
The patent dynamically adjusts the screen capturing frequency based on the detected content type. When action scenes are detected, the capturing frequency is increased to improve detection accuracy for fast-changing visual content. When static or slow-changing content is detected, the frequency is reduced to conserve power. This dynamic adaptation resolves the contradiction between maintaining high detection accuracy and reducing power consumption.
Solution Approach 2:
The patent changes the capturing frequency parameter according to the detected screen content characteristics. By monitoring content type and adjusting the capturing frequency parameter accordingly, the system optimizes the balance between detection accuracy (which benefits from higher frequency) and power consumption (which increases with higher frequency), achieving context-appropriate analysis depth.
